Method and Device for Latency Reduction of an Image Processing Pipeline

2. The method of claim 1, wherein the estimated composite setup time includes (A) a first time period for rendering the virtual content from the perspective that corresponds to the camera pose of the device relative to the physical environment during the first time period and (B) a second time period for compositing the rendered virtual content with the first image data.

4. The method of claim 1, wherein compositing the rendered virtual content with the first image data to generate the graphical environment for the first time period is based on a depth buffer.

7. The method of claim 6, wherein the threshold time is determined based on a refresh rate of the display device and pre-rendering latency.

8. The method of claim 6, wherein the device corresponds to a near-eye system that includes the display device.

9. The method of claim 1, wherein the first image data corresponds to one of a first slice of a first image frame or the first image frame.

11. The device of claim 10, wherein the estimated composite setup time includes (A) a first time period for rendering the virtual content from the perspective that corresponds to the camera pose of the device relative to the physical environment during the first time period and (B) a second time period for compositing the rendered virtual content with the first image data.

13. The device of claim 10, wherein compositing the rendered virtual content with the first image data to generate the graphical environment for the first time period is based on a depth buffer.

17. The non-transitory memory of claim 16, wherein the estimated composite setup time includes (A) a first time period for rendering the virtual content from the perspective that corresponds to the camera pose of the device relative to the physical environment during the first time period and (B) a second time period for compositing the rendered virtual content with the first image data.

19. The non-transitory memory of claim 16, wherein compositing the rendered virtual content with the first image data to generate the graphical environment for the first time period is based on a depth buffer.
